The Danish version of the questionnaire on pain communication: preliminary validation in cancer patients

Background: The modified version of the patients' Perceived Involvement in Care Scale (M-PICS) is a tool designed to assess cancer patients' perceptions of patient–health care provider pain communication process. The objective of this study was to examine the psychometric properties of the shortened Danish version of the M-PICS (SDM-PICS).
Methods: The validated English version of the M-PICS was translated into Danish following the repeated back-translation procedure. Cancer patients were recruited for the study from specialized pain management facilities.
Results: Thirty-three patients responded to the SDM-PICS, Danish Barriers Questionnaire II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory Pain Severity Scale. A factor analysis of the SDM-PICS resulted in two factors: Factor one, patient information, consisted of four items assessing the extent to which the patient shared information with his/her health care provider, and Factor two, health care provider information, consisted of four items measuring the degree to which a health care provider was perceived as the one who shares information. Two separate items addressed the perceived level of information exchange between the patient and the health care provider. The SDM-PICS total had an internal consistency of 0.88. The SDM-PICS scores were positively related to pain relief and inversely related to the measures of cognitive pain management barriers, anxiety, and reported pain levels.
Conclusion: The SDM-PICS seems to be a reliable and valid measure of perceived patient–health care provider communication in the context of cancer pain.     

SERUM LEVELS OF THYROTROPIN, THYROXINE AND TRIIODOTHYRONINE IN FULLTERM, SMALL-FOR-GESTATIONAL AGE AND PRETERM NEWBORN BABIES

Abstract. Simultaneous serum concentrations of TSH, total thyroxine (T₄) and triiodothyronine (T₃) were determined in 93 fullterm (FT), 37 small-for-gestational age (SGA) and 38 preterm (PT) babies with a postnatal age from 2 to 144 hours. In addition, TSH, T₄ and T₃ concentrations were measured in cord sera from 27 FT, 4 SGA and 5 PT babies and in venous blood from 20 mothers at delivery. Cord blood concentrations of TSH were higher and T₄ and T₃ concentrations were lower than seen in the mothers. Serum concentrations of TSH were high during the first day of life followed by a decline. There was no statistically significant difference between serum TSH concentrations of the three groups of newborns. On the 5th day of life no elevated serum TSH values were found in any of the groups (TSH<5mU/l). Serum concentrations of thyroid hormones increased after birth and reached maximum levels within 24 hours in all groups. The relative increases above cord level were of the same magnitude in the newborns: Two times for serum T₄ and six times for serum T₃. The thyroid hormone concentrations in blood samples from FT babies decreased from the second day of life, whereas in low birth weight newborns the decreases were more variable. The serum levels of T₄ and T₃ were significantly different in the three groups of newborns, the highest values were seen in FT and the lowest values in PT babies. In contrast, the ratios between molar serum concentrations of T₄ and T₃ were found to be highest in PT, lower in SGA and lowest in FT babies, approaching maternal values during the first week of life. The data are discussed with regard to hormone secretion, thyroxine-binding capacity and peripheral T₄ to T₃ conversion in the three groups of newborns. It is concluded that from day 5 after birth serum TSH determinations, alone or in combination with serum T₄, seem to be the method of choice in screening for congenital hypothyroidism.     

TREATMENT OF GIRLS WITH EXCESSIVE HEIGHT PREDICTION: Follow-up of Forty Girls Treated with Intramuscular Estradiol and Progesterone

Abstract. Andersen, H., Brock Jacobsen, B., Kastrup, K. W., Krabbe, S., Peitersen, B., Petersen, K. E., Thamdrup, E. and Wichmann, R. (Endocrine Clinic, Children's Hospital Fuglebakken, University of Copenhagen). Treatment of girls with excessive height prediction. Follow-up of 40 girls treated with intramuscular estradiol and progesterone. Acta Pædiatr Scand, 69:293, 1980.—In a follow-up study of 40 tall girls treated with intramuscular estradiol and progesterone, the final height, bone age maturation, side effects and acceptance of treatment were evaluated. The mean duration of treatment was 18 months. During treatment, mean height increase was 6.5 cm (height velocity 3.7 cm/year), which is nearly 50 % reduction of normal growth rate. The mean increase in bone age was 2.7 years (bone age velocity 1.8 years/year), which approximates twice the normal maturation rate. The mean reduction in final height was 5.0 cm as evaluated by the method of Bayley-Pinneau (BP), 2.9 cm by the method of Tanner et al. (TW) and 3.0 cm by the method of Roche et al. (RWT). The reduction was greatest when treatment was started before menarche, according to all three prediction methods. When treatment was started after menarche the calculated height reduction was greatest according to the BP method. There was good agreement between the three prediction methods in girls with a bone age below 12 years before treatment. In girls with a bone age above 12 years the height reduction by the BP method was much greater than when measured by the other methods. Side effects evaluated at follow-up were minimal and first menstruation occurred within 3 months (mean) after cessation of treatment. The number of pregnancies was estimated to be normal for age. All but three accepted the treatment. It is concluded that this type of treatment must be restricted to girls with severe psychological problems due to excessive height prognosis and selection for treatment must be based on an individualized evaluation.     

CHANGES IN SERUM CONCENTRATIONS OF THYROID HORMONES AND THYROID HORMONE-BINDING PROTEINS DURING EARLY INFANCY Studies in Healthy Fullterm, Small-for-gestational Age and Preterm Infants Aged 7 to 240 Days

Abstract. Serum concentrations of thyrotropin (TSH), thyroxine (T₄), triiodothyronine (T₃), thyroxine-binding globulin (TBG), prealbumin (TBPA) and albumin (Alb) were determined in 492 blood samples from 127 fullterm (FT), 91 small-for-gestational age (SGA) and 88 preterm (PT) healthy infants aged 7 to 240 days. Serum T ₄ decreased about 20% during the first month of life. In infants aged 7–49 days, serum T₄ concentrations were significantly lower in SGA than in FT infants, and even lower values were found in PT infants. Serum T ₃ increased 50–70% reaching maximal values by 50–79 days of life. Serum T₃ levels were higher in FT than in SGA infants throughout the observation period. In PT infants serum T₃ increased from low values to levels which exceeded those of SGA and FT infants by 120–240 days of life. Serum TSH level did not change with age and was 5 mU/1 in all infants. Serum TBG values were high compared to normal adult values and did not change significantly with age. Comparable serum TBG values were found in FT, SGA and PT infants. Serum TBPA increased with age. Serum TBPA increased gradually in FT infants. In SGA infants serum TBPA increased from low values to levels which by 120–240 days of life exceeded those of PT and FT infants. In PT infants a decrease in serum TBPA appeared before the rise commenced. Serum Alb increased gradually in FT, SGA and PT infants during the observation period. Serum Alb in PT infants aged 30–119 days was lower than those in FT infants with similar ages. These physiological changes in serum concentrations of thyroid hormones and hormone-binding proteins during early infancy should be considered when interpreting thyroid function tests in infants with various maturity.     

THYROTROPIN RESPONSE TO THYROTROPIN-RELEASING HORMONE IN FULLTERM, EUTHYROID AND HYPOTHYROID NEWBORNS

Abstract. The serum concentration of thyrotropin (TSH) and the TSH response following thyrotropin-releasing hormone (TRH) were studied in 16 euthyroid babies from 16 to 172 hours after birth and in 2 primary hypothyroid babies, 3 and 28 days of age. Serum-TSH was measured before an intravenous injection of 40 μug TRH and after 30 and 180 min. In the euthyroid babies increased basal levels of TSH were seen shortly after birth, followed by a pronounced decline. The extent of TSH increase after TRH could be correlated with the basal levels, and the relative increase was comparable to that which occurs in adults. In the hypothyroid babies very high basal levels of serum-TSH were seen, 125 and 400 μ/ml respectively, with no further increase following TRH stimulation. It was concluded that in euthyroid fullterm newborn, the relative response of serum-TSH to TRH was equal to that of adults, in spite of elevated thyroid hormone concentrations. In the hypothyroid newborn very high levels of serum-TSH were seen and a supplementary TRH-test seems without diagnostic value in congenital hypothyroidism.     

PRIMARY HYPERPARATHYROIDISM IN INFANCY ASSOCIATED WITH FAMILIAL HYPOCALCIURIC HYPERCALCEMIA

ABSTRACT. Clinical and biochemical evidence of primary hyperparathyroidism (prim. HPT) is reported in an infant with hypotonia, feeding problems and constipation from birth. Following a partial parathyroidectomy at the age of 12 months, the clinical condition improved. In her sister, mother and three other maternal relatives a familial hypocalciuric hypercalcemia (FHH) was subsequently demonstrated. All were clinically healthy in spite of increased total and ionized serum calcium, normal serum parathyroid hormone concentration, low urinary calcium excretion and normal renal excretion of cyclic AMP. Similar findings appeared in our patient after parathyroidectomy. An autosomal dominant inheritance of FHH is suggested. It is thus demonstrated, that a mother with FHH may give birth to healthy children with FHH as well as to infants with prim. HPT associated with FHH.     

EFFICIENCY OF TWO VARIABLE PERFORMANCE TECHNIQUES OF OXYGEN THERAPY IN RELIEVING POSTOPERATIVE HYPOXAEMIA

The efficiency of two patient-dependent, variable performancetechniques of oxygen therapy in relieving hypoxaemia after upperabdornir,al surgery was compared. A high-flow system delivereda humidified mixture of oxygen 2 litre min^–1 and air 13litre min^–1 through a cannula inserted into the anteriornares. The low-flow system delivered 2 litre min^–1 ofdry oxygen into the nasopharynx through a catheter. Thirteenotherwise healthy patients received either high-flow oxygentherapy for 30 mm followed by low-flow oxygen therapy for afurther 30 mm after operation or the same therapy in reverseorder. With the patients breathing room air, arterial hypoxaemiacould be demonstrated with Pao₂ inversely related to age. Theincrease of Pao₂ during either oxygen treatment was significantlygreater with the low flow system.
